Hi Bart,
as a first attempt, I've followed your steps, but got:
Error: could not find sg_reset
expectedly because of dependencies that you are implying in your steps.
So, I have followed the instructions in the srp-test README for the
case "Running the Tests on an Ethernet Setup", directly on a 4.16-rc1.
For ib_srp-backport, I get a lot of warnings like the following one,
at "make install" (preceded by corresponding warnings at the end of
the compilation):
depmod: WARNING: /lib/modules/4.16.0-rc1+/extra/ib_srp.ko needs unknown symbol
rdma_resolve_addr
Unfortunately, it gets worse while executing "make scst srpt":

Could you please give me some help, so as to not get lost among these issues?
Thanks,
Paolo
